Bus Éireann services have been disrupted in parts of Co Louth this morning due to an unofficial strike by drivers at the company's Drogheda depot.
All services from the depot have been cancelled since 7.30am.
The drivers took the action in support of another driver who was suspended after refusing to carry out a service.
A Bus Éireann spokesperson expressed regret at the disruption to services, and labelled the action "irresponsible and unnecessary".
